In what scenarios would using a .htaccess file for user authentication be more suitable than implementing a custom PHP login system?

Using a .htaccess file for user authentication would be more suitable in scenarios where you want to restrict access to certain directories or files on your website without the need for a full-fledged login system. This method is quick to set up and does not require any coding. However, if you need more advanced features such as user registration, password recovery, or user roles, implementing a custom PHP login system would be more appropriate.

// .htaccess file to restrict access to a directory
AuthType Basic
AuthName "Restricted Area"
AuthUserFile /path/to/.htpasswd
Require valid-user
